    Background: Current research suggests that the modern workforce is comprised of a substantial proportion of ageing employees, in addition to an influx of young, first-time workers. This diverse and multigenerational workforce provides organisations an interesting challenge, in retaining engaged and productive employees, and ensuring relevant training and development. One specific management practice is reverse mentoring. Reverse mentoring is a unique form of mentoring, whereby the traditional roles of mentor and mentee are reversed. It involves a junior employee (in age/status) mentoring a senior employee. The junior employee is able to share their recent generational learnings and perspective with a senior organisational member, who gains insight into recent trends and technologies. Whilst there appear to be many benefits from this relationship, including increased communication and understanding; leadership development; and upskilling in relevant trends, there may also be some barriers to the success of the relationship. Barriers may include a resistance to the shift in power hierarchy and challenges with changing the traditional learning pedagogy of older teacher and younger learner. Aim: Reverse mentoring is a reasonably modern concept, and as such, empirical research on this practice is relatively new. This research aims to explore any benefits and barriers experienced in a reverse mentoring relationship. Method: Participants in this study will be recruited from a Melbourne hospital, who currently run a formal reverse mentoring relationship program. Approximately 16 individuals (8 mentors and 8 mentees), will be invited to participate. The proposed study uses a qualitative method of data collection, through semi-structured interviews. Interviews will be recorded, and responses will be transcribed, with thematic analysis used to identify common themes. Thematic analysis allows the common themes and experiences of mentors and mentees, to tell an overall story of the data. Conclusion: The proposed study’s findings contribute to a currently small base of research on reverse mentoring. It is hoped that the research will help (i) inform future quantitative research on reverse mentoring and (ii) inform organisational strategies that will help employees engage in reverse mentoring relationships in ways that effectively support their training and development.

    While cities are generally major sources of anthropogenic carbon dioxide (CO2) emissions, recent research has shown that parts of urban areas may also act as CO2 sinks due to CO2 uptake by vegetation. However, currently available results are related to a large degree of uncertainty due to the limitations of the applied methods and the limited number of studies available from urban areas, particularly from the southern hemisphere. In this study, we explore the potential of eddy covariance and tracer measurements (13C and 14C isotopes of CO2) to quantify and partition CO2 fluxes and concentrations in a residential urban area in Auckland, New Zealand. Based on preliminary results from autumn and winter (March to July 2014) the residential area is a small source of CO2 (0.11 mol CO2 m-2 day-1). CO2 fluxes and concentrations follow a distinct diurnal cycle with a morning peak between 7:00 and 9:00 (max: 0.25 mol CO2 m-2 day-1/412 ppm) and midday low with negative CO2 fluxes (min: -0.17 mol CO2 m-2 day-1/392 ppm) between 10:00 and 15:00 local time, likely due to photosynthetic CO2 uptake by local vegetation. Soil CO2 efflux may explain that CO2 concentrations increase and remain high (401 ppm) throughout the night. Mean diurnal winter delta13C values are in anti-phase with CO2 concentrations and vary between -9.0 - -9.70/00. The depletion of delta13C compared to clean atmospheric air (-8.20/00) is likely a result of local CO2 sources dominated by gasoline combustion (appr. 60%) during daytime. A sector analysis (based on prevailing wind) of CO2 fluxes and concentrations indicates lower CO2 fluxes and concentrations from the vegetation-dominated sector, further demonstrating the influence of vegetation on local CO2 concentrations. These results provide an insight into the temporal and spatial variability CO2 fluxes/concentrations and potential CO2 sinks and sources from a city in the southern hemisphere and add valuable information to the global database of urban CO2 fluxes.

  • Development of an organisational memory scale

    Dunham, Annette (2007-12-06)

    Conference poster
    The University of Auckland Library

    In many countries, people are retiring earlier than ever before and the retirement of the baby boom generation over the next two decades further intensifies the impact of this trend. Accompanying this development, are fears about the potential loss of organisational knowledge or memory which may equate to the loss of the organisation’s competitive advantage. Organisations, while recognizing that older workers often possess valuable “organisational memory” seem to also assume these same workers will readily divest themselves of their knowledge. Encouraging experienced workers to act as a mentor to younger or less experienced workers, is often mentioned in the management and related literature as a way of capturing and retaining valuable organisational knowledge. However, employees (including older workers) in the possession of considerable organisational memory, may, or may not be willing to divulge their knowledge to others, for a number of reasons. This poster presents initial results from the first of a series of studies designed to examine the relationship between organisational memory in the individual and propensity to mentor. It outlines the development and exploratory factor analysis of an “Organisational Memory” scale that taps the individual’s own resources in terms of organisational knowledge and expertise. Subsequent studies in the proposed research aim to help organisations more effectively target potential mentors for the purposes of retaining organisational knowledge, while also identifying the relevant costs and benefits of mentoring perceived by those individuals. By doing so it is hoped organisations will have a clearer understanding of how they can minimize costs while emphasising the benefits of such a relationship for the potential mentor. In contrast to the “development outcomes” focus of much of the mentoring literature, these studies give attention to the “knowledge sharing role of mentoring, while also touching on developmental outcomes, in this case, for the mentor

    We report on an experimental method to measure conductivity of cortical tissue. We use a pair of 5mm diameter Ag/AgCl electrodes in a Perspex sandwich device that can be brought to a distance of 400 microns apart. The apparatus is brought to uniform temperature before use. Electrical impedance of a sample is measured across the frequency range 20 Hz-2.0 MHz with an Agilent 4980A four-point impedance monitor in a shielded room. The equipment has been used to measure the conductivity of mature mouse brain cortex in vitro. Slices 400 microns in thickness are prepared on a vibratome. Slices are bathed in artificial cerebrospinal fluid (ACSF) to keep them alive. Slices are removed from the ACSF and sections of cortical tissue approximately 2 mm times 2 mm are cut with a razor blade. The sections are photographed through a calibrated microscope to allow identification of their cross-sectional areas. Excess ACSF is removed from the sample and the sections places between the electrodes. The impedance is measured across the frequency range and electrical conductivity calculated. Results show two regions of dispersion. A low frequency region is evident below approximately 10 kHz, and a high frequency dispersion above this. Results at the higher frequencies show a good fit to the Cole-Cole model of impedance of biological tissue; this model consists of resistive and non-linear capacitive elements. Physically, these elements are likely to arise due to membrane polarization and migration of ions both intra- and extra-cellularly.

    Demographic evidence indicates that learners in Aotearoa-New Zealand are increasingly likely to speak more than one language and that this is most evident in the Auckland region. These trends suggest emerging challenges for researchers and practitioners. This poster presents our TLRI* research, in progress, which documents the diversity of language use and experiences of children in early childhood education and care in the Auckland region. The collaborative research team includes University of Auckland researchers and teacherresearchers in four early childhood centres: a Māori-medium centre, a Samoan immersion centre, and a kindergarten and a centre with children from a wide range of heritage language backgrounds. Theoretical frameworks influencing the design and analyses include an additive approach to bilingual activity and contexts that views children as potentially capable. The research (2013-2015) addresses three questions: 1. What languages do children from participating ECE centres use in their learning in the centre and at home? 2. What experiences and outcomes for children who learn in more than one language in the early years are valued by parents, teachers, and children? 3. How might the opportunities and challenges for children who learn in more than one language be addressed in educational practice? Objectives within each of the four partner-centre settings are to: · document the languages spoken by children, parents, and teachers in the ECE centre and at home · document and interpret the learning experiences of young children who learn in more than one language (as valued by parents, teachers, and children) · document the valued outcomes for young children who learn in more than one language · in partnership between teacher-researchers and University of Auckland researchers, analyse and theorise the data gathered, using funds of knowledge and additive bilingualism approaches, to build on understandings of the learning and teaching of children who learn in more than one language, and · analyse and theorise, using an 'additive approach' (to bilingualism, immersion, or multi-literacies), to extend understandings of the learning and teaching of children who learn in more than one language.) Research team members are using a range of qualitative and quantitative approaches to generate data about the experiences, opportunities, and challenges associated with learning in more than one language. Methods/tools include: questionnaires for parents and teachers, focus group interviews with parents and teachers, and fieldnote observations of arrivals and departures at the centres, videotaped observations of children's learning experiences in ECE settings, and conversations with children. In the poster session, aspects of these processes will be discussed. This research is significant, given the demographics and that there are gaps in current knowledge about learning experiences, valued outcomes and possible futures for children who are learning in more than one language in their ECE and (or) their family environments. Our study is designed to contribute new findings and to advance knowledge and practice about children learning in more than one language in the early years.

  • An Architecture for Flexible Problem Solving

    Langley, Patrick; Emery, Miranda; Barley, Michael; Maclellan, C (2013)

    Conference poster
    The University of Auckland Library

    The literature on problem solving in both humans and machines has revealed a diverse set of strategies that operate in different manners. In this paper, we review this great variety of techniques and propose a five-stage framework for problem solving that accounts for this variation in terms of differences in strategic knowledge used at each stage. We describe the framework and its implementation in some detail, including its encoding of problems and their solutions, its representation of domain-level and strategy-level knowledge, and its overall operation. We present evidence of the framework’s generality and its ability to support many distinct problem-solving strategies, including one that is novel and interesting. We also report experiments that show the framework’s potential for empirical comparisons of different techniques. We conclude by reviewing other work on flexible approaches to problem solving and considering some directions for future research.

  • Bridging the Computational Modelling and EHR standards using openEHR and Semantic Web Technology

    Atalag, Koray; Zivaljevic, Aleksandar; Cooling, Michael; Nickerson, David (2015-10-12)

    Conference poster
    The University of Auckland Library

    Linking clinical data to computational physiology will enable real-world model validation as well as the possibility of personalised and population level predictive decision support tools. Electronic health records (EHR) embody quantifiable manifestations of genomic and environmental aspects that impact on biological systems when clinical data are structured. However data quality and semantic interoperability remains a major challenge in the world of EHRs. In the computational physiology domain recent attempts to enable semantic interoperability heavily rely on Semantic Web technologies and utilise ontology-based annotations (e.g. RICORDO) but a wealth of useful information and knowledge sits in EHRs where Semantic Web technologies have very limited use. openEHR provides a set of an open engineering specifications that provides a canonical health record architecture and open source tooling to support data collection and integration. Core openEHR specifications have also been adopted by ISO and CEN making it a full international standard which underpins many national programs and has multi-vendor implementations worldwide. Our work describes how to use openEHR to normalise, annotate and link clinical data with biophysical models by using openEHR Archetypes as semantic pointers to underlying clinical concepts in EHR.

  • Comparison and refinement of hip joint centre prediction methods on a large contemporary population

    Zhang, Ju; Hislop-Jambrich, J; Besier, T (2014)

    Conference poster
    The University of Auckland Library

    The location of the hip joint centre (HJC) is critical for accurate lower limb kinematics. A number of methods allow the HJC to be predicted from the locations of bony pelvic landmarks. However, widely used predictions methods are often developed on small populations, or have inappropriate parameters when considering different populations. We compare the accuracy of prediction methods by Tylkowski[1], Bell[2], and Seidel[3], and update their parameters using a large urban population. 3-D models of the pelvis were automatically segmented from 159 (86 male, 73 female) post-mortem CT scans collected at the Victorian Insitute of Forensic Medicine. The dataset reflects a contemporary western urban adult population from the state of Victoria, Australia. Bony landmarks (ASIS, PSIS, symphysis pubis) were defined on an atlas model and propagated to correspondent positions on each subject-specific model. The three published methods above were used to predict HJC locations first using their published parameters, then using parameters fitted to the current dataset. Ground truth HJC locations were calculated as the centre of a sphere fitted to the acetabular regions of each model. Using published parameters, mean errors in millimetres for the Tylkowski, Bell, and Seidel methods were, respectively, 23 (4.9), 26 (4.1), and 18 (3.9). After fitting parameters to the current dataset, corresponding mean errors were 13 (5.5), 7.3(4.0), and 5.7 (3.3). Published parameter errors were similar to published errors for the Tylkowski and Bell methods, and more than twice that published for the Seidel method. After fitting parameters, errors for all methods were significantly lower than those previously published. These results highlight the need to validate and recalibrate joint centre prediction methods on large and population-specific datasets.

  • The STn-SNc hyperdirect pathway modulates dopaminergic neuron activity by inhibiting GABAergic inputs from the SNr via endocannabinoids

    Freestone, Peter; Wu, XH; de Guzman, G; Lipski, Janusz (2014-07-05)

    Conference poster

    The hyperdirect pathway of the basal ganglia circuitry terminates with a glutamatergic projection from the Subthalamic Nucleus (STN) to the Substantia Nigra pars compacta (SNc). We recently showed that glutamate released in the SNc drives endocannabinoid production in dopaminergic neurons, which in turn inhibits GABAergic transmission in that region. The present study investigated the potential role of STN glutamatergic projections of the hyperdirect pathway in this novel endocannabinoid modulatory mechanism. Whole-cell patch-clamp recordings were made from SNc dopaminergic neurons in horizontal brain slices (rat) containing STN, SNc and Substantia Nigra pars reticulata (SNr) regions. Either electrical (bi-polar electrode) or pharmacological (local carbachol application) stimulation of the STN was performed to evoke selective glutamate release from terminals in the SNc. GABAergic inputs to the SNc from the SNr were electrically stimulated to evoke inhibitory post-synaptic currents (eIPSCs). Single-pulse electrical stimulation of the STN caused transient (< 1 sec) attenuation of GABAergic eIPSCs amplitudes recorded from dopaminergic neurons (to 73% of control). The eIPSC attenuation was prevented by block of either cannabinoid CB1 receptors with rimonabant (3 µM) or metabotropic glutamate mGluR1 receptors with CPCCOEt (100 µM). Pharmacological activation of STN neurons by rapid local perfusion of muscarinic agonist carbachol (100 µM, 10 s) caused a similar attenuation of eIPSC amplitude. These findings show that glutamate release from STN terminals in the SNc modulates GABAergic transmission through endocannabinoid signalling – a previously undescribed function of the hyperdirect pathway.

  • Collaborative Problem Solving for Do-ers and Teachers of Mathematics

    This study sought to explore and analyse the phenomenon of maths anxiety within a real-life context, and to identify if levels of maths anxiety can be reduced through participation in a reciprocal teaching process. This poster presents a small element of the larger study, which investigated how to reduce maths anxiety in teacher candidates. Maths anxiety is a well-researched phenomenon that is known to impede the successful mathematics teaching and learning experiences of some teacher candidates. The maths anxiety these students bring to their mathematics education courses results in poor quality mathematics teaching (Biddulph 1999; Frankcom 2006; Sloan 2010). Mathematics education lecturers have become increasingly aware of how some students become visibly anxious when they walk into the mathematics classroom, and/or are asked to collaborate to solve mathematical problems. These observations are supported by the level of maths anxiety reported by these students. The model developed for this study was informed by the work of Palinscar and Brown (1984) and complemented by problem-solving models from Mullis, et al. (2008), Reilly, Parsons and Bortolot (2009), and Polya (1945). The Revised Reciprocal Teaching Model (RRTM) was designed is to facilitate teacher candidates’ access to mathematical practices used in schools, and simultaneously develop their personal mathematical knowledge and understanding. Cognisant of the problem solving and peer mentoring literature, researchers provided opportunities for graduates to develop adaptive expertise. While peer mentoring is thoroughly established in literacy education it is under-researched within mathematics education. Reciprocal teaching falls within this area of research and provides a framework for individuals to mutually support each other while learning. The RRTM was developed to promote discourse within mathematical communities in an attempt to reduce maths anxiety. The implementation of the RRTM was through a two-phased structured framework, designed to take place over a university calendar year. The framework began with specific training of peer mentors who in turn worked with assigned mentees. The second phase promoted less reliance on the peer mentors and resulted in the students forming their own peer mentoring groups outside of class time. Results suggest that the model has a positive effect on students’ ability to confidently talk about and solve mathematical problems. This is evidenced by the decrease in maths anxiety levels self-reported by teacher candidates. This research indicates the RRTM has the potential to reduce maths anxiety levels of teacher candidates and produce confident do-ers and teachers of mathematics.

    Background: There is little evidence on depression among men whose partners are pregnant or have recently given birth. Methods: An ethnically and socioeconomically diverse sample of 3528 men living in New Zealand completed interviews during their partner's pregnancy and nine months after the birth of their child. Depression symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) and the 9-item Patient Health Questionnaire (PHQ-9). Rates of depression (defined as EPDS>12 and PHQ-9>9) and associations with a range of paternal and maternal characteristics were explored using logistic regression. Results: Antenatal paternal depression, which affected 2.3% of fathers, was associated with paternal perceived stress (OR=1.4, 95%CI 1.3 to 1.5) and fair to poor paternal health (OR=2, 95%CI 1.1 to 3.5) during their partner's pregnancy. Postnatal paternal depression affected 4.3% of fathers and was associated with paternal perceived stress in pregnancy (OR=1.12, 95%CI 1.1 to 1.2), relationship status at nine months after childbirth (OR=5.6, 95%CI 2 to 15.7), fair to poor paternal health at nine months (OR=3.3, 95%CI 2 to 5.1), employment status at nine months (OR=1.8, 95%CI 1.1 to 3.1) and a past history of depression (OR=2.8, 95%CI 1.7 to 4.7). Conclusions: Expectant fathers are at risk of depression if they feel stressed or are in poor health. In this study, rates of depression were higher during the postpartum period and were associated with adverse social and relationship factors. Identifying who is most at-risk of paternal depression and when will help inform interventions to help men and their families.
